Kingsport Power, doing business in Tennessee as AEP Appalachian Power, has filed a request with Tennessee regulators under its existing tariff to pass through to retail customers a decrease in transmission costs.

The company is requesting an overall decrease of about 1.3 percent in electric rates effective Sept. 1.

Appalachian Power Company provides Kingsport Power with transmission and generation services under a federally approved Interconnection Agreement. The Tennessee utility owns no power plants and purchases all of its power from APCo at wholesale rates regulated by the Federal Energy Regulatory Commission.

Based on the filing, a Kingsport residential customer using 1,000 kilowatt-hours in a month can expect a bill of approximately $87.71, a decrease of $1.16 per month.

The company serves approximately 47,000 customers in East Tennessee.

Customers who have questions about their bill can contact the company on-line at www.appalachianpower.com or by phone at 1-800-967-4237.
